I should have said this previously, I have no real clue exactly what I
am doing, and I kludged this together from information I found on the

I originally didn't install the ATOM/PPS driver.  However when I
looked, I wasn't getting a PPS line ntpq.  Maybe that is ok, but I
assumed that meant it wasn't seeing the PPS and thus installed the
other driver.

You suggest that I get rid of the PPS driver, and just use the NMEA
driver.  Perhaps I didn't have a properly configured ntp.conf.

So if I go with your suggestion the appropriate NTP.conf would look
like this?

fudge stratum 5

server    minpoll 4       prefer  # NMEA serial port
fudge refid gps stratum 1

How can you tell when ntpd is receiving the PPS signal or not?

Thank you for your assistance in allowing me to muddle through this.
